Overview: DATASHEET ISLA224S
Dual 14-Bit, 250/200/125 MSPS JESD204B High Speed Serial Output ADC FN7911 Rev 2.00 April 25, 2013 The ISLA224S is a series of low-power, high-performance, dual-channel 14-bit, analog-to-digital converters. Designed with FemtoCharge™ technology on a standard CMOS process, the series supports sampling rates of up to 250MSPS. The ISLA224S is part of a pin-patible family of 12- and 14-bit dual-channel A/Ds with maximum sample rates ranging from 125MSPS to 250MSPS and shares the same analog core as Intersil's proven ISLA224P series of ADCs. The family minimizes power consumption while providing state-of-the art dynamic performance, offering an optimal performance-vspower trade-off.
Differentiating the ISLA224S from the ISLA224P is its highly configurable, JESD204B-pliant, high speed serial output link. The link offers data rates up to 4.375Gbps per lane and multiple packing modes. It can be configured to use two or three lanes to transmit the conversion data, allowing for flexibility in the receiver design. The SERDES transmitter also provides deterministic latency and multi-chip time alignment support to satisfy an application's plex synchronization requirements.
A serial peripheral interface (SPI) port allows for extensive configurability of the JESD204B transmitter including access to its built-in link and transport-layer test patterns.
